89630-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89630-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,3 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89630-68:
(7*8)+(6*9)+(5*6)+(4*3)+(3*0)+(2*6)+(1*8)=172
172 % 10 = 2
So 89630-68-2 is a valid CAS Registry Number.

Oxidative addition of chloro- and dichloroacetic acid to alkenes to give α-chloro- and α,α-dichlorobutyrolactones with manganese(III) acetate
Snider, Barry B.,Che, Qinglin
, p. 325 - 332 (2007/10/03)
Oxidative addition of chloroacetic acid and dichloroacetic acid to alkenes with Mn(OAc)3 to give α-chloro- and α,α -dichlorobutyrolactones proceeds in moderate to good yield in MeCN containing one equivalent of the sodium salt of the carboxylic
